LOWER SASH ROLL SCREEN Filed March 28, 1932 Patented June 29, 1933 UNITED STATES PATENT OFFIF.

HARRY DIXSON, OF PELLA, IOWA, ASSIGNOR TO ROLSCREEN COMPANY, OF PELLA, IONA, A CORPORATION ()F IOWA LOVJER SASH ROLL SCREEN Application filed March 28, 1932. Serial'No. 601,603.

The object of my invention is to provide a lower sash roll screen which is simple, durable and comparatively inexpensive to manufacture.

A further object is to provide a roll screen of the general type shown in my Patent No. 1,680,092, issued August 7, 1928 but which is adapted for screening only the lower half of a double hung window frame, or in other words, only the lower sash part thereof and to further provide such a roll screen which can be easily installed from the inside of the building in a minimum of time, thus eliminating the necessity for skilled installation and the use of ladders, etc. as when installing a screen from the outside of the building.

Still a further object is to provide a roll screen which includes a pair of guide receptors having flanges which may be secured to the facing surfaces of the blind stops instead of to the outside surfaces thereof, as in the patent mentioned, thus making it possible to install the guide receptors from the inside of the building.

Still a further object is to provide means for supporting the roll screen casing directly on the guide receptors so as to simplify installation and eliminate the necessity for securing the roll screen casing to the window frame after properly aligning it with the guide receptors, which would be a more difficult job and one requiring more skill.

A further object is to provide lips on the guide receptors to engage the top of the roll screen casing to retain it in position against dislodgment and to provide flanges on the upper ends of the guide receptors to support a spacing member which effectively fills the space between the roll screen casing and the meeting rails of the window so as to prevent the entrance of flies at this point.

Another object is to provide readily installed means for holding the screen in lowered position, such means being in the form of turn buttons pivoted to the window sill.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more.

fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 1 is an outside elevation of a window with my roll screen for screening the lower sash installed thereon.

Flgure 2 is an enlarged sectional view on the line 22 of Figure 1 showing the relation of the roll screen to the sill and meeting rails of the window.

Figure 3 is an enlarged sectional View on the line 33 of Figure 1 showing a guide receptor secured to the blind stop and a roll screen guide therein.

Figure 4 is a sectional view on the line 4-4 of Figure 2 showing the roll screen casing being installed on the guide receptors.

Figure 5 is a perspective view of the roll screen casing, upper end of the guide receptor and guide in separated position; and

Figure 6 is a perspective'view showing the upper end of the guide receptor, the roll screen guide and the spacing member in separated position.

On the accompanying drawing, I have used the reference character A to indicate a window. The window A includes a sill 10, a lower sash 12, an upper sash 14 and meeting rails 13 and 15 for the sashes 12 and 14, respectively. The blind stops at the sides of the window A are indicated at 16.

My roll screen includes a roll screen casing 18 from which a screen 20 extends having a binder 22 on its lower edge. The binder 22 has friction blocks 24 at its ends and is provided with a finger engaging lip 26 on the inside of the screen. My roll screen further includes guide receptors B and roll screen guides 28 and a spacing member 30.

The guide receptors B each comprise a mounting flange 32 a channel-shaped receptor portion having flanges 34 and 36 together with a flange 38 at the upper end of the mounting flange 32 and a lip 41 at the upper end of the channel flange 34.

The mounting flange 32 is provided with perforations 42 adapted to receive screws 44 or the like for mounting these flanges on the facing surfaces 16a of the blind stops 16, as best shown in Figures 2 and 3 of the drawing.

Thus it will be obvious that the receptor members B may be easily and quickly mounted relative to the window A and the mounting operation can be performed from the inside of the building with the lower sash 12 in raised position. This eliminates the necessity for mounting the guide receptors on the outer surfaces of the blind stops as shown in my prior patent.

After the guide receptors are mounted in their proper positions, the roll screen guides 28 are inserted between the flanges 34 and 36 thereof, the guides themselves having flanges 29 for this purpose. The guides also have slitted tubular guide portions 31 for the edges of the screen 20 and for the binder blocks 24.

After the guide receptors are in mounted position and the guides 28 are in position, the roll screen casing 18 may be supported thereon by inserting flange portions 19 thereof (which extend beyond the ends 21 of the roll screen casing) between the upper ends of the flanges 34 and 36 as shown in Figure 5. In this figure the flange 19 is ready to enter between the flanges 34 and 36 by a downward motion of the roll screen casing.

I have out the upper ends of the flanges 36 at an angle 36a so that the roll screen casing can be installed without necessarily holding it in a level position as shown in Figure 4. The edges of the flanges 36 which engage the ends 21 are the proper distance apart to just allow entry of the ends between them and therefore the casing could be installed only while being held level if it were not for the angles 36a at which the flanges 36 are cut. This is best illustrated at the right side of Figure 4.

After the roll screen casing 18 is in position with flanges 19a of the roll screen casing resting on the upper ends of the flanges 36, the lips 41 are bent from the dotted line position of Figure 2 to the full line position, as indicated by the arrow (1 to retain the roll. screen casing in position. During the insertion of the roll screen easing into the guide receptors B, the friction blocks 24 enter the tubular guide portions 31 of the screen guides 28 and after the casing is installed, the binder 22 may be lowered for properly adjusting the width between the screen guides 28, the binder blocks 24 accomplishing this purpose. The screen guides 28 are frictionally held between the flanges 34 and 36 to retain such 1 adjustment and yet permit re-adjustment when contraction or expansion of the win dow varies the actual distance between the guide receptors B.

It will be noted that the roll screen casing 18 is comparatively small since enough screen is rolled therein to screen the lower half only of the window. It will also be noted that it is located adjacent the meeting rails 13 and 15 of the window sashes. These characteristics make it comparatively incon spicuous and in fact much neater in appearance than the wood frame of an ordinary window screen.

When the roll screen casing is mounted on the outside of the blind stops, as disclosed, however, there is a space between the roll screen casing and the meeting rail 15. I have provided the spacing member to fill this space, the member itself being a strip of wood or the like of the same width as the blind stop. On the upper ends of the mounting flanges 32 of the guide receptors 13 I have provided the flanges 38 to support the ends of the spacing member 30. The flanges 38 may be perforated as indicated at 40 to receive screws or the like 46 extending up into the spacing member 30 to prevent its dislodgment upwardly when the upper sash 1 1 is raised from a lowered position.

The tubular portions 31 of the roll screen guides 28 are cut off at an angle 31a at their upper ends to facilitate re-entry of the screen into the guide after it has once been knocked out of the guide. Referring to Figure 3, it will be noted that the edge of the screen is provided with a staple 48 and in fact there are series of these longitudinally spaced along the edge of the screen to normally retain the edge of the screen in the guide. The guide, however, is resilient so that the staples can be pulled through the slit opening of the guide if the screen is accidentally pushed against and this eliminates pulling the staples out of the edge of the screen.

Then when the screen is rolled up, the staples enter over the angle portion 31a and enter the roll screen casing in the ordinary manner.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modifled forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.
